I believe NXT has hit an all time low. With Ardor about to be released I put a bit of money into this today.
My NXT is currently sat on Poloniex. Have instructions been released on how these coins will be swapped for Ardor?
You don't need to do anything, exchanges like Poloniex will automatically add Ardor in your account and the amount you will get will be equal to your current NXT balance with the ratio of 1:1.
